WEATHER STRIP.

Application led March 4, 1927. Serial No. i72,665.-

invention relates to weatherstrips and4 more particularly to metal weatherstrips adapted to'be applied to easement windows, doors and the like for the purpose of rendering them weather tigh, Heretofoie, such weatherstrips of this type as 'have been provided for use either have been ineffectualV in Aoperat-ing to ren- 1,.

der the windowl or door weather .tight or l0 have been ofY such f complicated form or shape as tomake them top expensive in manufacture and in application to the' .25 Fig. 1.is a fragmentary elevation of my weatherstripin place on the window; Fig. 2 is asection alon the line 2-2 in Fig. 1; and Fig. 3 shows 1n detail'one of the'component partsof the weatherstrip. l

Referring to the figures the weatherstrip comprises an upper member A attached to the window sash B by nails C or any other suitable means, and a lower member D attached to a part of the window frame E, preferably, by screws F. `The upper member A has an outwardly projecting water shed G, and the longitudinally extending rib H which has the inner end, the end nearest the axis of the window, of the edge 4o thereof bent downwardly, as is clearly shown -at M in Figs. 2 and 3. The lower rmember D has the upwardly extending part J which terminates at its upper end in the inwardly projecting longitudinally extending rib K. Weep holesl L may lie-'provided `in the lower` member D so that'any water condensing therein'or oollectin inthe gutter thereof when vthe window is open may drain therefrom. e

The ribs H and K ongthe upper and lower members, respectively, are preferably formed as shown withv the edges thereof thicker than the base thereof so that the upper surface of the outer edge of the lower rib "is normally in a plane above the plane of the lower surface of the upper rib', all for the id., However, the upper member A need not be as rigid as the lower member but, to

.and in cont-act with the thinner base of the purpose as fully hereinafter set forth. Also, I prefer, that the member D be made of thick metal so as to be substantially rigthe contrary, I prefer that it be formed of metal thinenough to g'ive the rib H substantial resilience. 1

The operation ofthe weatherstrip embodying my invention is as follows :'-The members A and D are attached to the window sash. and the window frame,'respectively, so that the rib K is slightly higher than the ribv H, as shown in Fig. 2. When the window sash is swun on its hinges since the inner end vof the rib H is bent downwardly,

as described above, the inner end will be below the rib K andas the window is closed the inner end will be introduced under the rib K. As the closing of the window continues and since the rib H is resilient the whole rib H will be gradually introduced under the rib K, and when the window is in closed position the two ribs will be in interlocking engagement with the thick edge of the rib H lying next to and in contact with the thinner base of the rib K, and with the thick edge of the rib K lying adjacent to rib H, all as shown in Fig. 2. I prefer that the part of the upper member A just above the rib' H be formed to follow the contour of the edge of the-rib K and to be in contact therewith when the ribs are in interlocking engagement so that no water or air -may flow Vinwardly past the top of the rib K. While, I prefer, that the thick edges of the ribs H and K. are formed thick enough to form an interlocking engagement between the ribs, they are notto be so thick as to make such a tight interlocking engagement that when the window is opened they will not be easily carried out of engagement with one another. Also, I prefer that the edges of the ribs be rounded, as

,shown, so that when the window is closed the ribs will not butt Ybut their shape will move the edges thereof past one another into an interlocking engagement, as described above.

In order that no water may flow between the upper member A and the'face of the window sash B I prefer that the upper member A be bent slightly inwardly and 'embedded in the sash B whereby thejointbetween the upper` member and the window sash B will be flashed. Also, I prefer that the water shed G extend outward-ly a substantial distance so-thatfrain and wind to a used effectiiallly at the top "of the Casementwindow and by forming the ribs H and K so 'that they may be easily' moved into inter- 'locking engagement-the weatherstrip may be i'ised' along the side'of the window oppo- Isite to the side which is hinged to :theframe lVhatl' claimI as new and desire to secure vby Letters-Patent, is
